Politeness!
Rejection note from the publisher to the author while returning the script:
We have perused your manuscript with exceptional relish. We fear, however, that if we were to publish your outstanding work, it would be quite impossible for us to ever again publish another work that would not come up to its standard. And we cannot imagine how any other work will be its equal in the next hundred years! So, to our deepest regret, we are compelled to return your incredible composition. And we beg you a thousand times over to pardon our shortsightedness and faintheartedness.
Politeness should not diminish the clarity of Truth.
